The overall efficiency of a grid-connected photovoltaic power generation systems depends
on the efficiency of the DC-into-AC conversion. This paper presents a comparative study of …

This paper proposes the speed control of a separately excited dc motor varying armature
voltage. The novelty of this paper lies in the application of nonlinear autoregressive-moving …

In this study, electromechanical equations of separately excited DC motors are examined
and the exact electrical equivalent circuit related to mechanical equations is introduced. The …

Many industrial applications require the use of power electronic devices, which in turn help
in overcoming the problems of variable load and fluctuations that occur at the end of feeding …

This paper introduces the new concept of Artificial Neural Networks (ANNs) in estimating
speed and controlling the separately excited DC motor. The neural control scheme consists …

The current review aimed to: i) Simulate the work of electronic transformer; ii) Analyze and
design different types of electronic transformer; and iii) Identify the most important joints of …

This paper presents the position control scheme of DC servo motor drive. The fuzzy PI
controller is developed for controlling the position of DC servo motor drive. The DC servo …
